STM6779 Overview
7 1.1.1 Active-low, push-pull reset output (RST) - STM6718/20/78/80 . 7 1.1.2 1.1.3 Active-low, open drain reset output (RST) - STM6717/19/77/79 . 7 Push-button reset input (MR).
STM6779 Key Features
- Primary supply (VCC1) monitor. Fixed (factory-programmed) reset thresholds: 4.63 V to 1.58 V
- Secondary supply (VCC2) monitor (STM6717/18/19/20/77/78)
- Fixed (factory-programmed) reset thresholds: 3.08 V to 0.79 V
- Tertiary supply monitor (using externally adjustable RSTIN): 0.626 V internal reference
- RST outputs (push-pull or open drain); state guaranteed if VCC1 or VCC2 ≥ 0.8 V
- Reset delay time (trec) on power-up: 13.2 ms, 210 ms, 900 ms (typ)
- Manual reset input (MR)
- Optional delayed manual reset input (MRC) with external capacitor (STM6777/78/79/80)
- Low supply current
- 11 µA (typ), VCC1 = VCC2 = 3.6 V
